Highway Noise Barrier System JINBIAO

Main Components of Highway Noise Barrier Systems
• Foundation System

Includes pile foundations, concrete bases, embedded steel plates, and anchor bolts to ensure structural stability.

• Support System (Steel Columns)

Usually made of H-shaped steel columns, supporting the barrier panels and resisting wind loads.

• Barrier Panel System

Sound-Absorbing Panels: Perforated metal panels filled with rock wool or glass wool to absorb traffic noise.

Sound-Insulating Panels: Directly block sound transmission.

Composite Panels: Combine sound absorption and insulation functions.

• Auxiliary Components

Transparent Panels: PMMA acrylic or laminated glass for visibility and noise reduction.

Top Structures: Curved or angled caps to improve acoustic performance.

Sealing System: Bolts, clips, and EPDM rubber strips to prevent sound leakage.

Barrier heights are commonly between 1–5 meters and can be customized in color and design.

Installation Steps of Highway Noise Barrier Systems
1. Measurement & Layout

Mark foundation and column positions according to design drawings.

2. Foundation Construction

Install pile foundations or chemical anchor bolts, then pour and cure concrete.

3. Column Installation

Lift and fix H-shaped steel columns, adjust alignment and verticality, then secure firmly.

4. Bottom Sealing

Install rubber pads or sealing strips to reduce sound leakage.

5. Barrier Panel Installation

Install panels from bottom to top and fix them with clips or brackets. Insert EPDM sealing strips between joints.

6. Top Structure Installation

Install curved caps or sound-absorbing top structures if required.

7. Final Inspection

Check alignment, sealing performance, bolts, and overall installation quality before project completion.

Note: Installation methods may vary depending on road type, foundation structure, and panel materials, but the general process remains similar.
